Study of relationship between quality of life and BMI subject of seminar

08 Sep 2010

CHEPA’s monthly seminar series for 2010-11 will kick off on Sept. 22 with a presentation on the trajectories of health related qualify of life for men and women in relationship to body mass index (BMI).

David Feeny, a founding member of CHEPA who is now senior investigator and assistant program director at the Kaiser Permanente Northwest Center for Health Research in Portland, Ore., will discuss a study that examined the changes in BMI and health related quality of life (HRQL) over an eight-year period.

The study analyzed data from the longitudinal Canadian National Population Health Survey. Analyses are based on data for 3,864 males and 4,745 females who were older than 40 in 1998/99. The Health Utilities Index Mark 3 was used to measure HRQL in relationship to five categories of BMI: underweight, normal weight, overweight, obese class I and obese classes II and III.

Feeny will describe the analysis process and the results, which showed that in general there was a decrease in HRQL with age, but for men, there was a more substantial decrease among those who were underweight. Among women, being underweight was associated with modestly higher HRQL at younger ages, but a substantial decrease at older ages.

The implications of these results will also be presented.

The seminar will be held in Room B119 of the Communications Research Laboratory, from 12:30 p.m. to 1:30 p.m. All are welcome to attend.

Feeny is an emeritus member of CHEPA, and taught at McMaster University from 1976 to 1998. He is also a professor emeritus at the University of Alberta. He has a master’s degree and a PhD in economics from the University of Wisconsin-Madison.

During his career he has conducted numerous research studies on health economics, health-related quality of life, health services, health technology assessment, health technology policy and institutional change.

Feeny’s visit to McMaster is being co-sponsored by the Departments of Economics and Clinical Epidemiology and Biostatistics.
